Concerning oocyte competence, the presence of LH receptor is associated with the dominant status in bovine and other mono-ovulating species [9, 136, 163]. The dominant follicle in bovine occurs at the average diameter size of 8.5 mm and is associated with an increase capacity to generate compe...

It is proposed that the first follicular phase in the lamb is initiated when responsiveness to oestradiol inhibition of LH secretion decreases sufficiently to permit the expression of an inherent hourly LH pulse rhythm. The hourly LH pulse rhythm is believed to drive oestradiol production to levels ...
So if you have high FSH or TSH levels when testing with an OPK, the test will report those levels as LH only. This could get afalse positive result, making you believe you’re having an LH surge when you’re not. Whereas if you were to test your LH with a fertility monitor likeIni...
Administration of a single dose (50-100 μg/kg BW) of the antagonist SB-75 inhibited effectively the elevated gonadotrophin levels for 48 h. Pituitary LH and FSH content was not affected by SB-75 treatment. When administered in the early afternoon of the proestrus to intact cycling rats, ...
If E2 is primarily responsible for the LH surge, we would expect that a follicle would develop but ovulation and leutinization would not occur when estradiol levels were lowered by continuous daily letrozole. DESIGN: Prospective. MATERIALS AND METHODS: Ten healthy ovulatory volunteers with regular ...
